NOTE
Compliance to EN61000-4-2,3,4,5; ENV50204, EN55024, Light industry level, criteria A 330.8K hrs min. MIL-HDBK-217F (25 99*97*36mm (L*W*H) 0.39Kg; 45pcs/18Kg/0.9CUFT )
DIMENSION PACKING
1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
